Specification of Letters Patent.

Patented Sept. 5, 1905,

To It 1071mm it many cone/Wm Be it known that l, \VILLLm T. H ULsonnR, acitizen of the United States, residing at the city of Battlecreek,county of Calhoun, State of Michigan, have invented certain new anduseful Improvements in Bailing-Presses, of which the following is aspecification.

This invention relates to improvements in baling-presses. It relatesparticularly to improvements in baling-chambers for balingpresses.

The main object of this invention is to provide an improvedbilling-chamber for balingpresses in which the completed bale isautomatically ejected when the door of the chamber is opened or isfreed, so that it may be readily withdrawn.

Further objects and objects relating to structural details willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is fully illustratedin the accompanying drawings, forming a part of this specification, inwhich Figure 1 is a detail side elevation view of a structure embodyingthe features of my invention. Fig. 2 is a detail horizontal sectionalview taken on a line corresponding to line 2 2 of Fig. l, the door ofthe baling-chamber being shown open and the walls in their distendedposition, the door and walls being indicated in their closed position bydotted lines. Fig. 3 is a detail longitudinal sectional view taken on aline corresponding to line 3 3 of Fig. 4. Fig. i is a rear end elevationview looking from the right of Figs. 1 and 3.

In the drawings the sectional views are taken looking in the directionof the little arrows at the ends of the section-lines, and similarletters ofreference refer to similar partsthroughout the several views.

Referring to the drawings, the frame A of my improved baling-press ispreferably made of angle-iron. B represents the hopper. The

forward end or feed portion B of the hopper is provided with suitablewalls, which are rigidly secured to the frame. The portion of thechamber in which the bale is formed is provided with hinged side wallsI) and hinged bottom wall T. The side walls and also the bottom arepivoted upon bolts S, which are passed through the frame. (See Figs. land 2.) A pair of stops S is provided for the side walls to limit theiroutward movement. A crosspiece C is provided toward the rear of thebaling-chamber to support the bottom when in its open position.

The walls of my improved baling-chamber are preferably made of sheetmetal. The side walls .1) are made up of longitudinal strips D and endpieces l)", of angle-iron, to which the sheet-metal lining is secured.The walls of my improved baling-chamber are thus very rigid and durableand at the same time comparatively inexpensive.

The door F is made up of an angle-iron frame on which the strips (i aresecured. The door F is hinged on a pivot-bolt or rod L, similar to thepivot-bolts or rods S for the side walls.

Blocks or cams 1 and 0, having inclined faces, which are adapted toengage the projecting ends ll of the side walls and force them intotheir closed or operative position as the door is closed, are carried onthe door. (See Fig. 2.)

The cam P is arranged on the hinged side of the door and is providedwith a double face, as it is necessary that the same engage the sidewalls, substantially as shown, as the door begins to close. blocks orcams R, having inclined faces, which are adapted to engage and lift thebottom T to its closed position when the door is closed, are alsocarried by the door. Thus arranged, when the door is closed .the wallsare all returned to their closed or operative positions and are retainedthere by the door.

A lever K, adapted to engage the door after the same is partially closedand force the same to its closed position, is provided. This lever ispivoted on the rod or bolt L and is also adapted to retain the door inits closed position. A catch ll, pivoted on the door-pivot L, isprovided to engage the end of the lever. The end of the lever K isbeveled, so that as the catch ll is forced upon the same it has acam-like action and forces the lever inward.

\Vith the parts thus arranged after a bale is completed the catch ll iswithdrawn from the lever K, which allows the door to swing open, therebyreleasing the walls, the rear l portions of which swing outward,completely releasing the bale. The bottom T, dropping down against thecross-piece C, causes the halo to slide from the chamber. Under ordinarycircumstances the bale is thus automatically ejected. However, shouldthe same not move automatically from the chamberit is freed, so that butlittle force is required to start the same.

My improved balingrpress is very economical to produce and is also veryeasy to operate and also may be operated very quickly.Althoughcomparatively light, it is strong and durable, the parts notbeing subjected to any unusual strain or wear.

I have illustrated and described my improved baling-chamber forbaling-presses in detail in the form preferred by me. I am aware,however, that it is capable of considerable structural variation withoutdeparting from my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a baling-chamber, the combination of a suitable frame; side wallsand a bottom for said chamber, pivoted to said frame at their forwardends; suitable stops for said side walls and bottom; an end door hingedto said frame; blocks or cams having inclined faces carried by said dooradapted to engage said side walls and bottom to return them to andretain them in their operative position when the door is closed, for thepurpose specified.

2. In a baling-chamber, the combination of a suitable frame; side wallsand a bottom for said chamber, pivoted to said frame at their forwardends; an end door hinged to said frame; and blocks or cams, havinginclined faces, carried by said door adapted to engage said side wallsand bottom to return them to and retain them in their operative positionwhen the door is closed, for the purpose specified.

8. In a baling-chamber, the combination of a suitable frame; wallshinged to said frame at their forward ends; an end door pivoted to saidframe; and blocks or cams on said door adapted to engage said walls toreturn them to their operative position when the door is closed, for thepurpose specified.

4. In a baling-chamber, the combination of a suitable frame; wallshinged to said frame at their forward ends; and an end door adapted toengage said walls to return them to their operative position when thedoor is closed, for the purpose specified.
